Bus connections en route

[Richard Sampson]

I will be walking a part of the Camino this September with my two adult daughters and with
my brother from SJPP to Castrojerez, since that is the only time we have this year.  (My
wife and I walked from Roncevalles to Santiago may-june 2001.)  But one of my daughters has
even less time and wants to go to Madrid from a point about Belorado or Santo Domingo. Are
there bus connections from either of these towns to either Burgos or Madrid?  Richard
